Control optionsPressure & Flow (Load Sense) Compensator for AEC018 AG variant only

The Agricultural tractor variant of 220 pump has a shuttle valve integral into pump end cover which senses the highest load of the two-work circuit and a priority valve to set the flow priority . For tractor application steering is given priority over other auxiliary functions like hitch circuit for implements .

Fluid output from the pump end cover enters into the priority valve before reaching to system . Integrated priority valve gives the pump flow priority to Steering system over the Hitch valve of the tractor . The shuttle valve senses highest of the two load pressures (Steering load or Hitch system load) and gives the load sense signal to flow control of the pump to adjust the pump flow as per the load requirement . The load signal is carried through steel pipe from end cover to pump controller .

These features make this pump suitable for other platforms where shuttle and priority valve are required .

The pump will provide flow & pressure matching of pump output to system load demand, maximizing efficiency and improving load metering characteristics of any directional control valve installed between the pump and the load . Load sensing ensures that the pump always provides only the amount of flow needed by the load . The pump operating pressure adjusts to the load pressure plus a pressure differential required for the load sense margin . When the system is not demanding flow, the load sense control will operate in low pressure zero flow, energy saving stand-by mode . The differential pressure is the difference between the pressure inlet and service port of a proportionally controlled directional valve, or a load sensing directional control valve . See the model code for differential pressure settings for load sensing . If the load pressure exceeds the system pressure setting, the pressure compensator reduces pump displacement . The load sensing line must be as short as possible and can also be used for remote pressure control or unloading of the pump pressure . For remote pressure control purposes, it is recommended that you contact your Eaton Representative for the correct configuration of the control .

Warning:

• When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement . It is possible to adjust the pressure compensator beyond the rated pressure of the pump . Doing so, may void the warranty of the pump .

• EATON recommends use of relief valve in all systems .

Pressure limit settings

The pressure compensator uses two springs to cover the full pressure range of the X20 pumps .

Spring 1 = < 140 bar (2050 psi)

Spring 2 = 145 - 280 bar (2100 - 4060 psi)

Flow Compensator (Load Sense) settings

There are two springs used to cover the load sense adjustment range of this control . Available load sense range is

Spring 1 = < 20 bar (290 psi)

The pump will provide a con tinuously modulated flow to meet changing load demands at a pre-adjusted compensator pressure . At pressures below the compensator setting, the pump will operate at maximum displacement . See model code position #16, 17 for compensator pressure ranges .

Warning:

• When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement . It is possible to adjust the pressure compensator beyond the rated pressure of the pump . Doing so, may void the warranty of the pump .

Remote relief valve is to be connected to pilot port “J” through necessary external piping . Standard differential pressure of 20 bar is set at RPC spool . The required outlet pressure (below 280 bar) can be set by adjusting remote relief valve setting . Once pressure reaches preset value, flow across remote relief valve starts, this results in RPC spool movement due to pressure imbalance . This will de-stroke the pump to maintain the set pressure .

Secondary fixed pressure compensator is provided to limit the max pressure setting as a fail safe measure .

Note

• Flow Compensator is not available with RPC .• When selecting this option in the model code, a pressure

setting value must be identified in the flow compensator field . Select a range of 10-24 bar (140-350 psi), default is 20 . The setting selected is the RPC differential pressure .

• Remote relief valve is not included in supply scope of the pump .

Pump displacement can be controlled infinitely, as per the current signal provided to the solenoid control valve . The integrated pump control makes use of an external current signal to vary the pump displacement . This control has an proportional characteristic i .e . with increasing current signal, the displacement increases proportionately .

This control is with manual override . Based on fail safe condition there are two types:

Min type (EP): Return to min displacement in case of power loss . Max type (EPD): Return to max displacement in case of power loss

Warning:

• When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement . It is possible to adjust the pressure compensator beyond the rated pressure of the pump . Doing so, may void the warranty of the pump .

The EH Inverse Proportional Pressure control allows for stepless variation of the max pump output pressure, as per the current signal provided to the control valve solenoid .

The integrated pump control makes use of an external current signal to vary the pump output pressure

This control has an inverse proportional characteristic i .e . with increasing current signal, the max output pressure is proportionately reduced

Warning:

• When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement . It is possible to adjust the pressure compensator beyond the rated pressure of the pump . Doing so, may void the warranty of the pump .

• EATON recommends use of relief valve in all systems .

Pressure limit settings

The minimum is 110 bar and max pressure can be set from 140 bar (2050 psi) to 280 bar (4060 psi) .

Typ. Current vs pressure characteristics of IPPC at 1800 rpm at various max pressure settings at 49 deg C (120deg F), static conditions.

Installation and start-up

Warning: Care should be taken that mechanical and hydraulic resonances are avoided in the application of the pump . Such resonances can seriously compromise the life and/or safe operation of the pump .

Drive data

Mounting attitude should be horizontal (shaft parallel to the ground) using the appropriate case drain port (furthest from the ground) to ensure that the case remains full of fluid at all times . If mounted with shaft upward (shaft perpendicular to the ground) the shaft end case drain (option G or H) must be used .

In those cases where geometric tolerances of mounting are critical, or where specific tolerance ranges are required and not specified, consult Eaton Engineering for specific limits .

Direction of shaft rotation, viewed from the prime mover end, must be as indicated in the model designation on the pump– either right hand (clockwise) or left hand (counterclockwise) .

Direct coaxial drive through a flexible coupling is recommended . If drives imposing radial shaft loads are considered, please consult your Eaton Representative .

Start-up procedure

Make sure the reservoir and circuit are clean and free of dirt/debris prior to filling with hydraulic fluid .

Fill the reservoir with filtered oil and fill to a level sufficient enough to prevent vortexing at the suction connection to pump inlet . It is good practice to clean the system by flushing and filtering, using an external slave pump .

Caution: Before the pump is started, fill the case through the uppermost drain port with hydraulic fluid of the type to be used . The case drain line must be connected directly to the reservoir and must terminate below the oil level .

Once the pump is started, it should prime within a few seconds . If the pump does not prime, check to make sure that there are no restrictions between the reservoir and the inlet to the pump, and that the pump is being rotated in the proper direction, and that there are no air leaks in the inlet line and connections . Also check to make sure that trapped air can escape at the pump outlet .

After the pump is primed, tighten the loose outlet con nections, then operate for five to ten minutes (unloaded) to remove all trapped air from the circuit .

If the reservoir has a sight gage, make sure the fluid is clear– not milky .

Fluid cleanliness

The X20 Series pumps are rated in anti-wear petroleum fluids with a contamination level of 21/18/13 per ISO 4406 . Operation in fluids with levels more contaminateda than this is not recommended . Fluids other than petroleum, severe service cycles, or temperature extremes are cause for adjustment of these codes . Please contact your Eaton Representative for specific duty cycle recommendation .

Eaton X20 Series pumps, as with any variable displacement piston pumps, will operate with apparent satisfaction in fluids up to the rating specified here . Experience has shown however, that pump and hydraulic system life is not optimized with high fluid contamination levels (high ISO cleanliness codes) .

Proper fluid condition is essential for long and satisfac tory life of hydraulic components and systems . Hydraulic fluid must have the correct balance of cleanliness, materials, and additives for protection against wear of components, elevated viscosity and inclusion of air .

Essential information on the correct methods for treating hydraulic fluid is included in Eaton publication 561 – “Eaton Guide to Systemic Contamination Control” – available from your local Eaton distributor . In this publication, filtration and cleanliness levels for extending the life of axial piston pumps and other system components are listed . Included is an excellent discussion of the selection of products needed to control fluid condition .
